GABA Cells Help Fight Alcohol Dependence,

Scientists of the Higher School of Economics, Indiana University, and École Normale supérieure clarified how alcohol influences the dopamine and inhibitory cells in the midbrain that are involved in the reward system and the formation of dependency on addictive drugs. 

New Drug Significantly Slows Progression Of ALS

A new drug could significantly slow the progression of ALS, also known as Lou Gehrig's disease, according to new research by University of Alberta biologists. Current treatments slow progression of the degenerative disease by only a few months and these findings could revolutionize the treatment of patients suffering from ALS, extending and improving quality of life.

Disruption of Circadian Rhythm: A Risk Factor for Diseases

USC scientists report that a novel time-keeping mechanism within liver cells that helps sustain key organ tasks can contribute to diseases when its natural rhythm is disrupted. This dual function of the nuclear receptor protein HNF4A offers a potential explanation for diseases such as diabetes and cancers. It also helps explain why such maladies are more common for people living with disrupted sleep, including night-shift workers, urban dwellers, and international jet-setters.

Teens get More Sleep With Later School Start Time

When Seattle Public Schools announced that it would reorganize school start times across the district for the fall of 2016, the massive undertaking took more than a year to deploy. Elementary schools started earlier, while most middle and all of the district's 18 high schools shifted their opening bell almost an hour later—from 7:50 a.m. to 8:45 a.m.

New Method Helps Better Understand Pathological Development of ALS

The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with the muscles as their axons atrophy. Researchers at Karolinska Institutet have now devised a new method that radically improves the ability to study axons and thus to better understand the pathological development of ALS. The method is described in the scientific journal Stem Cell Reports.
